Photographic lighting system

Abstract

A plurality of vertical supporting members are upstanding from a base or support to define a parallepiped and adjustably support a plurality of horizontal supporting rods for providing a structure for enclosing an object to be photographed, the structure being adapted to position lighting means, camera means and related means relative to the object. The crossbeams can be removably mounted on said horizontal supporting rods for adjustably supporting lights, reflectors, cameras, objects to be photographed, and other accessories, such as roll curtains and backdrops. An elongated natural daylight source is preferred.

What is claimed is: 
     
       1. In a photographic structure for positioning lighting means, camera means, background material and an object to be photographed in preselected positions relative to each other, and the like, the combination of vertical and horizontal supports, and releasable means for holding the vertical and horizontal supports in various selected assembled parallelepiped relations, so that the supports can be quickly and adjustably assembled to enclose a relatively small object to be photographed in a fixed position within said assembled supports, a relatively small object fixedly mounted on said supports, means to adjustably support lighting means on said structure in fixed selected locations relative to the fixed object to be photographed within said structure to provide desired lighting thereof, lighting means mounted on said means to adjustably support lighting means, means to adjustably support in fixed position selected background roll curtain material on said structure relative to the object to be photographed in various preselected positions, and roll curtain means mounted on said means to adjustably support in fixed position selected background roll curtain material. 
     
     
       2. In a photographic structure for positioning lighting means, camera means, background material and an object to be photographed in preselected positions relative to each other, and the like, the combination of vertical and horizontal supports, and releasable means for holding the vertical and horizontal supports in various selected assembled parallelepiped relations, so that the supports can be quickly and adjustably assembled to enclose a relatively small object to be photographed in a fixed position within said assembled supports, a relatively small object fixedly mounted on said supports, elongated gaseous discharge fluorescent-type lamp means with natural daylight emitting properties, means to adjustably and slidably support said lighting means on said structure in fixed selected locations relative to the fixed object to be photographed within said structure, means to adjustably support in fixed position selected background roll curtain material on said structure relative to the object to be photographed in various preselected positions, and roll curtain means mounted on said means to adjustably support in fixed position selected background roll curtain material. 
     
     
       3. In a photographic structure as claimed in claim 2 wherein the lamp means has a color rendering index of at least 80 together with transmission of middle ultraviolet in the range of about 6 to 50 microwatts per lumen of visible light and about 150 - 700 watts of near range ultraviolet radiation per lumen of visible light and the radiant power ratio of near ultraviolet to middle ultraviolet radiation in the range of between 8 to 40 so that the quantity of ultraviolet radiation is approximately the same per lumen as in natural daylight of the correlated color temperature. 
     
     
       4. In a photographic structure as claimed in claim 2 wherein the lamp means are slidably mounted adjacent the ends thereof on said supports so that the lamp means can be adjusted to fixed positions to illuminate the object to be photographed.
